---------------------------------------------------------------------- Date: Mon, 1 Feb 1999 17:41:04 -0800 From: John_E_Schnupp at amat.com Subject: re: GFCI I got a reply today and wanted to post my response. It's not specifically beer related, but in that it is a response to a very real electrical safety concern, I think that I should post it. After all I'll bet that every homebrewery has at least some electrical equipment, and some of the RIMS and plastic pail brewers use electricity almost exclusively. >an industrial electrician by trade. The only thing I can think I work in field service in semiconductor manufacturing equipment. I work with everything from 5VDC to 480VAC. Voltages inside individual components can exceed several kVAC (ion implanters microwave generators and RF generators). I also work with the whole range of super nasty, kill you with a whif arsine, to the more friendly nitrogen (which can kill you if you are in an enclosed area with no oxygen supply). Some of the robotics used on some of the equipment can injure too. There's vacuum (high and low), pressurized gases and liquids, high and low temps (1200 degC to 10 degK). In fact, just the other day we had a quartz chamber implode. Is was running about 15 liters/min HCl, 10 liters/min H2 at 660 Torr (almost atmospheric pressure) at 1200 degC. Talk about a hazard, and that's just due to the gas and temperature, not to say anything about all the broken quartz. Could have been worse, had it been at a lower pressure and the force of the implosion would have sent the quartz shards really flying. Oh, yeah, I forgot all the nasty liquid chemicals like HF and H2O2, for example. Then there's all those weird by-products (that they don't even know what they do to ya') and chemical interactions. My point, just wanted to give you a little background on where I'm coming from. Maybe this explains my concern for safety. In my job what you don't know really can kill you. >Isn't death more likely under rather extreme circumstances? Not that Not really. I can't find the booklet we got in out live electrical training class, but I do believe it's in the range of 100-500 mA that will kill. It takes even less to start heart fibrillation, which is serious enough to cause death if a regular heartbeat is not re-established. Granted a lot depends upon the current path but most times it's not in one finger and out the one next to is. It's more likely that the path is thru one had to the other or thru a hand to a foot, both of which basically place the heart right smack dab in the middle. But wait you say, doesn't the current flow mostly on the skin? Actually the skin is less conductive than the electro-chemical soup inside the skin, and 60 Hz penetrates skin much more easily than the 50 Hz that is used in most of the rest of the world. Here's a quick question. What special tools are needed to work on a live electrical circuit? >I want to stick my tongue in a wall socket, but my step-father is an >electrician, and I've *seen* him look for live wires by touching >them bare-handed! "Yup! That's it!" The correct way to look for live wires is with a VOM. (answer to above question, once you have determined the problem using the meter, you should use lock out tag out procedures and turn the power off) If you really need to get the adrenaline rush then make sure you use the back side of your hand/fingers or a very fast swiping motion. Your muscles work by electrical impulses from your brain. They constrict when activated. the signal input from a live wire will over ride the signal from your brain (by the virtue of being stronger) and cause your muscles to contract. If you use the palm side of your hand the resulting action will be a clenching of the hand into a fist. Using the back of the hand caused the fingers to be "automatically" removed then the hand clenches. When using a rapid swiping motion, hopefully, the momentum of your hand/arm will be sufficient to carry your hand away from the electrical device. me> eyes will explode right out of their sockets. >Urban legend. The jury is out whether or not it even happens to those >sentenced to die that way, where the exposure is very long and the <snip> >Exactly. The liquid in your eyes is miniscule at best compared to the >rest of your body. You'd have to heat the whole thing up, the eyes >don't just volunteer to be heated first. As liquid water doesn't >expand or contract much, the liquid in the eyes would have to literally >boil, rather than simply heat up, for this to be true. You'd be long >dead before any liquid in your body boiled. Ok I'll give you that one. I was just repeating something that was told to me in a safety class here at work. Looks like I'm guilty if keeping an urban myth going. me> even by a little bit and the pressure on the eyeball increases dramatically me> according to PV=nrT. >If'n I remember my freshman chem correctly (I probably don't!), poovnert >applies only to gases (?) I thought Bernoulli did liquids (When the >velocity of water goes up, the pressure exerted actually goes *down*. >That is, if one were to neck a 6" pipe down to 4" and run water through >it, the pressure on the 4" pipe will be lower than in the 6". Believe >it or don't!). PV=nrT relates pressure, volume and temperature. I do believe that this relationship is true for solid, liquid or gas. Your example is relating velocity and pressure, and I yes I do believe it, but I think it was Venturi who discovered this. Maybe Venturi did it for gases and Bernoulli did it for liquids. My carburetor on my Harley operates on this effect. The throat of the carb is tapered (large to smaller). As the air flows thru it, it passes by a hole which creates lower pressure in the narrow portion of the carb throat. This reduced pressure lifts a needle out of a hole and allows gas to be "sucked" into the air stream. me> Electricity really is take way too lightly by>> way too many people. >Agreed! On this point we agree. The real problem is the most people are ignorant about electricity. It is the ignorance that breeds complacency.

Date: Tue, 02 Feb 1999 12:43:28 +1100 From: John Coulter <jac at mira.net> Subject: Re: Head retention on stout Jim Kingsberg asks about improving head retention on stout/ales. I posted on this last year and got some helpful replies which I'll summarize. One said forget brewing extract and go to all-grain. Another said brewing with extract is fine and take no notice if anyone says otherwise. Another said try bottled water.(which I haven't done yet) Others talked of the importance of mashing in any flaked barley (which I do but more for taste/clarity reasons as it hasn't made much difference to the heading properties). Another reply referred to some articles in Brewing Techniques about nitrogenating beer and stout (www.beertown.org/indexframeset.htm then choose the letter N from the list and scroll untill you see the Nov/Dec 1997 issue and select it.) These articles were very helpful. I make a guinness style stout, using light extract and added grains (roasted and flaked barley etc) and keg the results with a N/CO2 mix. After reading the articles I purchased a carbonation stone which I used to nitrogenate the stout and found that it made a significant difference to the head retention. I had lots more tiny bubbles dissolved in the brew which helped keep the head alive after pouring. Before using the stone I could still pour a perfect creamy head but it didn't last long enough. Now it will outlast a can of imported Guinness with the widget. I'm convinced there's more nitorgen dissolving in the stout than previously with my static nitrogenation( apply pressure and leave for a few days like I do with my beer). Maybe there's other ways to get the same result but this one worked for me. John Coulter Melbourne, Australia (80 degrees warmer than wherever Jeff Renner lives) Return to table of contents

I actually have a beer bullet, but didn't know what to call it up until now. My wife used to grumble every time she saw the brewing stuff come up from the basement. Louder grumbling when the brewing smells filled the house. Then one day I won a couple of awards in a competition. One prize was a gift certificate for a brewpub in NYC.

Date: Mon, 1 Feb 1999 00:04:42 -0500 From: Steve <steves at ro.com> Subject: Re: George De Piro's comments on "Kelly's stuck lager..." George De Piro writes in HBD #2942: "2. You mention that the high-gravity batch was relatively free of break material while the other was not. Break can serve as both a yeast nutrient and a CO2 nucleation site. Too much CO2 does inhibit fermentation. Agitating the carboy twice per day may release enough CO2 to allow the ferment to finish. Good beer can be made this way (I've done it, as have many others)." I've read in various sources about "rousting the yeast" by agitating the carboy after the airlock has quieted down, but the specific gravity hasn't dropped as much as expected or hoped for. My thought when reading George's post was that the symptom, treatment, and effect are the same regardless of either cause ("too much CO2" or tired/lazy/slacker yeasties). In the past, I've tried the "swirl the carboy base on a tennis ball while holding the carboy neck semi-stationary" method with uncertain results (lacking a twin control batch). I'm guessing that George (help me here, please) would agitate the almost-beer without fear of oxidation 'cause there shouldn't be much O2 in the headspace, while the "yeaster roustabouts" would be attempting to re-suspend the whole yeast cake so that the kids who were stuck on the bottom could get some more food. I will covet the comments of the congregation and choir. Steve Stripling Huntsville, AL OK, I'm sneaking a second question in, but it's concerning the same quote. Do the sweet, precious little yeasties get more/better/different nutrition from hot break or cold break? Reason I axt is 'cause while I was (oh, man, two brews and I lapse into vernacular) typing the first question, I was also trying my first starter wort pressure-canning 'speriment and noticed there was some break material in the bottom of the Mason jars before they cooled enough to touch. (I can't see this effect at the end of the boil in my kettle, so until now it was just theoretical.) Since I use an immersion chiller on brew day, I combine both hot and cold break in the pot. Swirling would mix these more completely, so I don't. I usually try to rack out only a bit of the break from the top (based on references similar to George's "yeast nutrient" comment). OK, for those of you who forgot the question (me too), it's the second sentence of this paragraph. Again coveting comments. - --------------------------------- Return to table of contents
Date: Mon, 1 Feb 1999 00:05:35 -0500 From: Steve <steves at ro.com> Subject: Re: Bottling bucket necessary? Jeff Renner comments on bottling in HBD #2942: >"Gregory M. Remake" <gremake at gsbalum.uchicago.edu> asks: >I've always racked my wort from the secondary carboy to a bottling bucket >for bottling. Is this step necessary? and lists the advantages he forsees and asks for disadvantages. One good thing about racking once more is that you can bottle with a lot less yeast carryover. When I bottled, I would fine with gelatin in the secondary, which gave me nearly crystal clear beer (usually ales) over a firm yeast sediment. I managed to have no more yeast in the bottle than the thickness of a coat of paint. Aesthetically pleasing. Gives a clear glass of beer with no careful decanting. Jeff (end of quote) Question: How do we know that we have enough sexy yeast getting into the priming vessel? I usually let the beer hang in secondary till it drops fairly clear (2-3 weeks at 66-72F for ales) and rack off, trying to miss the cake. Then wait at least three weeks after bottling to test the first one. My timing is based on the confidence that the yeast know what they're doing. But just like some of the rest of us, managers (that would be me in this case) don't let us do our job properly. Rules of thumb work about 75% in my case. So, how do we know?

At first glance I took his message to be just a troll, but I've spent quite a bit of time surfing his web site over the past year, and I know he works for an electrical contractor who specializes in industrial controls (among other things). He seems to know his stuff. His site includes several interesting and entertaining brewing-related devices, including a very creative and sophisticated RIMS. I'd like to welcome Wayne to this forum. I feel he could be a valuable resource to us and I look forward to future posts from him. Until then, check out his web site for some great info. http://andinator.com/zymico By the way...I absolutely agree with him on the importance of proper bonding!

Date: Tue, 2 Feb 1999 08:30:37 -0500 From: larson.jt at pg.com Subject: Fermentation question Suddenly, my fermentations seem to be taking a really long time. I ferment in the basement, where temperatures stay 65-68f, and my secondary has gone from a historical 1 week to 4 weeks+. My last two batches will not stop bubbling (not a ton; maybe on bubble through the airlock every 2-3 minutes). In the past, all pressure and activity would subside within 7-10 days. Is this a sign of infection? Should I cool them down to halt activity? The only change to my process for the last two batches is a switch to a converted keg brew kettle and full 5 gallon boils. Cooling occurs quickly with an immersion chiller. Does this observation signal a problem or does everything sound ok? (these are partial-mash ales with Irish or British Wyeast and I have historically not taken gravity readings) On a seperate note, I am having trouble maintaining a good siphon coming from the brew pot. On the inside, I use 3/8" copper tube to extend down from the ball valve to a screen system on the bottom. To maintain a siphon, I use a piece of 1/2" clear tubing on the outside that gets too flexible when siphoning sparge or mash water to a cooler (it bends and kinks). Is there a better alternative that is flexible enough to get a good siphon going, but firm enough to handle easily when hot? All input is greatly appreciated.

In HBD 2943, "Christopher Tkach" <tkach at mediaone.net> asks of me: >Just a quick question... Do you find it takes longer to bottle condition >when you fine w/ gelatin? Approx. how long? I've never done a side by side comparison, so I can't say. I almost never bottle anymore, but I don't recall ever waiting more than 10 days to 2 weeks. There is plenty of yeast suspended in visually clear beer to get the job done, although I generally managed to disturb the sedimented yeast in the secondary with the racking cane enough to transfer a little sedimented yeast, too. When judging, I am often amazed at the thick layer of fluffy yeast on the bottom of bottles, making it difficult to pour a clear beer, especially if, as is often the case, it is highly carbonated and the evolving fizz stirs up the yeast. With a little patience, it is easy to greatly reduce the yeast. Jeff -=-=-=-=- Jeff Renner in Ann Arbor, Michigan c/o nerenner at umich.edu "One never knows, do one?"

Date: Tue, 02 Feb 1999 13:48:49 +0000 From: AJ <ajdel at mindspring.com> Subject: Bleach pH John McLeod's suggestion that people not acidify bleach solutions should generally be adhered to but I'll stick to my assertion that acidification can be done quite safely if care is used. In the Jan 15 post I guessed that an ounce of 5 trade percent (typical household strength) bleach in a gallon of water should give a pH of about 9. Experimentation confirms this, with my water at least (pH approximately 6, alkalinity about 80). I measure 8.95. At this pH at 25C only 3% of the hypochlorite is in the desireable (bug slaying) hypochlorous acid (HOCl) form, the rest being hypochlorite ion (OCl-). Thus though one has about 350 ppm chlorine at this dilution only 10 ppm are in the most lethal form. Lowering the pH to 7 with a little acid will increase the percentage of HOCL to 80%, to pH 6, 97% and though there is little point in going lower pH 5 gets you to 99.7%. The effect of this on the bugs can be judged from the Ct values I posted on Jan 15. Dilute solutions like this seem to be capable of acidification to pH 3 or less before disproportionation takes place (chlorine bubbles form). Perhaps I was not clear that the pH adjustment must be done after dilution. With stronger solutions, it's a different matter. The country's worst water plant chlorine release occured when a truck driver accidentally dumped ferric chloride (an acid salt) into a hypochlorite tank resulting in a precipitous drop in pH to 5 and the sudden release of 12,000 pounds of chlorine gas [White, "Handbook of Chlorination and Alternative Disinfectants" Wiley, N.Y. 1999 p113]. You can reproduce this event in miniature in your kitchen by adding hardware store strength (8 N) hydrochloric acid to full strength household bleach. Don't do it! Return to table of contents
Date: Tue, 2 Feb 1999 08:49:22 -0500 From: David Whitman <dwhitman at rohmhaas.com> Subject: Gibberellic Acid Cliff Moore is having trouble dissolving the gibberellic acid he bought for malting experiments. I don't know enough biology to advise how to use the stuff on seeds, but I can help get it in solution. >From the Merck Index, 11th Edition: >>>> Gibberellic Acid ...Slightly soluble in water, ether. Freely soluble in methanol, ethanol, acetone. Moderately soluble in ethyl acetate. Soluble in aqueous solutions of sodium bicarbonate and sodium acetate. >>>> That last line is the approach I'd take. Sodium bicarbonate (baking soda) is cheap and non-toxic. Make up a stock solution of 5% or so baking soda, and use that as your solvent. Your serial dilution approach makes perfect sense if you don't have access to an analytical balance good enough to do a direct weighing. I wouldn't use a strongly basic (or acidic) solution to dissolve gibberellic acid; try to keep pH between 5 and 9. There's a lactone ring on there that could get hydrolyzed and a couple other sites on the molecule that look like prime rearrangement candidates.

Date: Tue, 02 Feb 1999 07:13:11 -0700 From: The Brews Traveler <BrewsTraveler at adamsco-inc.com> Subject: Re: Too cold Lagering I once found out by accident and the beer turned out to be one of my best (funny have some of your best brews are totally unreproducable). I brewed a Rauchbier and was awaiting delivery of a new chest freezer, with the addition of a Johnson temp. controller, was to be my beer fridge. Expecting a speedy delivery I brewed the beer and let it sit at basement temps (~60) for a couple of days. With the freezer nowhere in site I iced it down to ~45 where it sat for a couple more days (where is that delivery guy???). The freezer arrived and I hooked up the control, and set it to 45, and put the (glass) carboy inside. It appeared that the (new) controller wasn't behaving well since the temperature appeared to be rising and falling too much but being a trusting person I cranked it down to 35. The next morning I awoke to check the temperature and it was ZERO DEGREES. The beer was not slushy but frozen solid! Fortunately the carboy was not cracked so I returned the defective controller for one that worked. The beer turned out great so I named it: Fire, Smoke, and Ice Rauchbier!

Date: 02 Feb 99 08:01:26 -0800 From: "Eric Schoville" <ESCHOVIL at us.oracle.com> Subject: False Bottom Sorry I am late responding to the false bottom thread, but I'm going to contribute my 2 cents anyway. Originally I used a manifold for my brewing kettle (outdated pictures still available at my website). It left quite a bit of wort in the bottom of the kettle, but otherwise worked well with whole hops or plugs (I don't use pellets). I didn't like the fact that it was not easy to remove to clean the kettle well, so I thought about a false bottom. I ended making a false bottom out of an aluminum pizza pan with holes in it. I had two problems. First, the pizza pan would not fit through my opening. Second, I had to figure out a way to drain from the bottom of the boiler, since the coupling is in the side of the keg. My solution was to cut the pizza pan in half and then screw the halves back together using a 2" aluminum strip with SS self tapping screws. Next I put together some copper pipe in an L shape to go to the direct bottom of the boiler. See a picture of an identical one that I use on my HLT at my website below. In order to get the FB around the tube, I unscrewed one half from the aluminum strip, and then drilled a hole in the aluminum strip to accomodate the copper pipe. Then I cut out the hole with a jigsaw so that half could be placed around the tube. Afterwards, I screwed on the other half. The first couple of times it didn't work as promised because there weren't enough holes. So I spent many hours drilling the SOB until it is as holey as Swiss cheese. Anyway it works very well now, and there is hardly any wort in the bottom of the boiler. It is also very easy to remove and clean. I am thinking about putting a false bottom in my mash tun, but for the time I spent, I think I am going to go with a commercial model! See you guys at the MCAB!

Date: Tue, 02 Feb 99 11:06:04 PST From: "George De Piro" <gdepiro at fcc.net> Subject: Bottling buckets and secondaries / wheat as an adjunct Hi all, There has been a bit of discussion about the use of bottling buckets and secondaries. People are justifiably concerned about oxidation of the fermented beer when using such vessels. Oxidation of fermented beer is indeed a horrible thing. It can rob your beer of malt character and even give it metallic and sherry-like flavors. It is best to avod it. That is why I have taken to using kegs as secondaries and bottling buckets (I thank Bill Coleman for the idea of using a keg as a bottling bucket). A keg is easily purged of oxygen by filling it with boiled water and pushing the water out with CO2. The hot water also serves to sanitize the clean keg. This is much more effective than simply pressurizing the keg a few times. If you think this is too anal, some mega-brewers take the care to do this with 500 bbl tanks. My 10 gallons of homebrew is easily worth the extra effort. After purging the keg it is filled with beer and primings (if you are bottling). This can be done through the "liquid out" fitting (simply put the "CO2 in" fitting on the keg as a vent). The keg is then sealed with a few pounds of CO2 pressure and shaken to mix the primings. You can then attach your bottle filler to the "liquid out" and let 'er rip (unless you are using the keg as a secondary, obviously). If you are really anal you can use your counterpressure filler as a bottling device, purging each bottle with CO2 prior to filling it. In this way you should be able to get close to mega-brewer levels of air in your bottled beer. Sure, this degree of analness is not necessary if you plan on keeping your beer cold and drinking it within a month. For those of us who keep beer around longer or don't have a dedicated beer refrigerator, this degree of care can increase the shelf life of your beer. See George Fix's article in the Nov./Dec. issue of Brewing Techniques for data showing the startling rate of decline in the flavor of aerated beer. - ----------------------------------------------------------------- Regarding Jim's question about wheat as an adjunct: it does not have to be cooked like rice and corn. Wheat gelatinizes at or below saccharification temperature (52-64C, 125.5-147F), so it can be milled and used in an infusion mash (you will probably want to use a protein rest when using large quantities of raw wheat).

Date: Tue, 2 Feb 1999 13:28:22 -0500 From: "Jeff Beinhaur" <beinhaur at email.msn.com> Subject: Spruce Beer Jon asked about using spruce. I brewed a batch of a honey/spruce beer and as one of my skiing buddies said, "it was like skiing through the trees with your f*&king mouth open". Another friend relayed to me that it was a good solution to rid his yard of slugs. My wife compared it to drinking PineSol (now how she knows what PineSol tastes like is still a bit of a concern on my part). Never the less I would highly recommend that if you use the liquid form, essence of Spruce which is a milky looking solution, you use a very, very, very small amount. I used about a third of the bottle (sorry don't know the exact size but it was a small container probably no more than an ounce) in a five gallon batch. Good Luck...

It seems that I have a stuck ferment, I was wondering if anyone had any ideas as to what happened and what to do about it. 17 Jan - made a 9-10 gallon batch of porter: 8.6kg HB pale ale 550g black patent 500g 80L crystal 285g DWC caramel pils 115g Briess carapils 260g chocolate 7.5 gal very soft water treated with 1.25 tsp epsom salts 0.75 tsp baking soda, 0.5 tsp canning salt. Mash in with same treated water to achieve 152F mash temp. Added 2.5 tsp chalk to get pH up to 5.2. 40 minutes into mash, temperature down to 148-149F. 90 mins- converted, surface temperature down to 144F. Raised to mash-out of ~165F, held for 5 mins then recirc'd - ranoff into kettle. Boiled for 60 mins, with 85g EKG for 60 mins, 45g Fuggle for 10 min and 30g Fuggle at 0 mins. 1/2 tsp Irish moss added with 15 min left in boil. Topped up with water to ~11 gallons at 1.060. Whirlpooled and rested wort for 5 mins, then ranout through CF to ~68F into two 23L carboys (one then the other). Shook carboy vigorously for 15 mins then pitched 2 pkgs of Danstar London dry yeast, rehydrated in 104F water for 15 mins. Placed in room at 68F to ferment. 21 Jan - krausen has risen and fallen (note: long lag time ~ 12 hrs), bubbling every 40 secs. Temperature has held at approx. 65-66F. SG taken: 1.025. Increase room temp to 68F, rouse yeast by swirling. 26 Jan - SG still 1.025, add a pkg of Cooper's dry (note: after pitching, noticed that yeast had expiry date of Jan '99.. also not stored in fridge by shop). 30 Jan - SG still at 1.025 1 Feb - (evening) add 1 pkg of fresh, properly stored Cooper's yeast, rehydrated as above. 2 Feb - (morning) no activity. I'm beginning to wonder if 1.025 really is the terminal gravity. However, with a mash temp of 152F down to 144F over 90 mins, I really doubt that 58% AA is likely. I suppose it possible that my thermometer is out, but it would have to be out by around 6-7 degrees F. Any thoughts here? cheers, Dave Riedel Victoria, BC, Canada Return to table of contents

Message-ID: <19990201.220435.-276943.3.Haafbrau1 at juno.com> Well, first off, Rob Moline was right about needing 5 lbs pressure to seal the keg initially. As far as the build-up of CO2, if you had the two beers connected together, and you consumed the first to bleed off the excess pressure, you'll eliminate the build-up pressure problem.8-) But seriously, what I've done in the past with still-fermenting kegs is just bleed off CO2 after about 20-25 psi, down to about 8 lbs and start over. Not much else I can say on the matter, I'll leave that to the 'experts'. Hope this helps.

Date: Tue, 2 Feb 1999 15:13:55 -0500 From: Ryan McCammon <mccammon at isr.umich.edu> Subject: use of copper in brewing I am a little confused about the safe use of copper in brewing. According to the Michigan State University Extension (http://www.msue.msu.edu/msue/imp/mod02/01500616.html), the FDA says that "the agency cautions against using unlined copper for general cooking because the metal is relatively easily dissolved by some foods and, insufficient quantities, can cause nausea, vomiting and diarrhea." What are the implications of this warning for my copper immersion chiller? What about for my buddy's amazing 12 gallon copper kettle? What about the beer from the wort that I boiled in this unlined copper kettle? Since wort is acidic, it seems to me that it should readily dissolve some of the copper. OTOH, I thought that the Brits referred to their brewpots (or is it fermenters?) as 'coppers', owing to the traditional use of copper for such purposes. What gives? Return to table of contents

Remake" <gremake at gsbalum.uchicago.edu> Subject: More bottling questions Hi all, Thanks for your responses regarding the need for using a bottling bucket. Most felt that it's worth doing, primarily to ensure complete mixing of the priming solution, and minimizing yeast transfer. Some others prefer priming the bottles directly, and filling straight from the carboy. I think I'll give it a try sometime, but as I suspected, there are valid reasons for using the bottling bucket. Some additional questions: I'll be bottling my first lager after a few weeks in the secondary, after I've fined with gelatin. I'm assuming there should be enough yeast left in suspension, but should I stir up some of the settled yeast during racking, just to be sure? To help carbonate the bottled beer, should I store it at room temperature (or some other temperature) prior to cold conditioning, or just go straight to cold conditioning (at 35F)?

Is it used >commercially in its soluble form? The company I work for uses Gibberellic Acid as part of its cultivation practices in growing table grapes and tree fruit (nectarines, peaches, plums, etc.). The farmers call this stuff Gibb (jib) and classify it as "enlargement" (no Fouch, don't go there) and a growth regulator. I believe they spray it on after it has been diluted in water and buy it in liquid form. The application rate is something like 1 pint per acre. One acre typically yields 600 boxes of fruit, and each box is about 20 lbs. As part of my job I have to analyze the economic net effect of using this chemical on the final product. There is no question of its value added, and that the net effect is larger more marketable fruit. I used to think Gibb was a bunch of hooey until I had to analyze its costs and benefits. Clif, let me know if you want me to find out the exact application rates. Kyle Bakersfield, CA Return to table of contents
